Fronthaul Quantization-Aware MU-MIMO Precoding for Sum Rate Maximization
Yasaman Khorsandmanesh, Emil Björnson, Joakim Jaldén
This paper considers a multi-user multiple-input multiple-output (MU-MIMO) system where the precoding matrix is selected in a baseband unit (BBU) and then sent over a digital front…

MSE Minimization in RIS-Aided MU-MIMO with Discrete Phase Shifts and Fronthaul Quantization
Parisa Ramezani, Yasaman Khorsandmanesh, Emil Björnson
In this paper, we consider a downlink multi-user multiple-input multiple-output (MU-MIMO) communication assisted by a reconfigurable intelligent surface (RIS) and study the precodi…

Joint Discrete Precoding and RIS Optimization for RIS-Assisted MU-MIMO Communication Systems
Parisa Ramezani, Yasaman Khorsandmanesh, Emil Björnson
This paper considers a multi-user multiple-input multiple-output (MU-MIMO) system where the downlink communication between a base station (BS) and multiple user equipments (UEs) is…
